A military helicopter crashed in southern Maryland on Monday, authorities said.

Maryland State Police spokesman Sgt. Davaughn Parker said a Black Hawk helicopter crashed in Leonardtown on Monday afternoon. He said state police have sent two medevac helicopters to the scene to assist.

Kevin Bowen, who works in the pro shop of the Breton Bay Golf and Country Club in Leonardtown, said he saw the helicopter "flying kind of low" and then "saw it spinning" before it went down between the third and fourth holes of the golf course.
